The create_db_and_tables function is now called on app startup using the FastAPI on_event decorator. This ensures that the database and tables are created before the app starts listening for requests.
Description
This pull request implements the NodeToolbar feature and migrates the
dialog UI to shadCN. The NodeToolbar introduces three actions:
duplicate, delete, and edit. The edit action allows users to modify the
advanced configuration of the tools. Additionally, this pull request
migrates the dialog UI to shadCN, specifically updating the prompt
dialog, code dialog, export dialog, python functions dialog and
tooltips. These enhancements improve the user experience and provide a
more efficient and modern interface.
Changes Made
Added NodeToolbar component to the application.
Implemented duplicate functionality, allowing users to create copies of
the selected nodes.
Implemented delete functionality, enabling users to remove selected
nodes.
Implemented edit functionality, providing users with the ability to
modify the advanced configuration of the tools.
Migrated the prompt dialog UI to shadCN, improving its appearance and
functionality.
Migrated the code dialog UI to shadCN, enhancing its usability and
aesthetics.
Migrated the export dialog UI to shadCN, resulting in a more streamlined
and intuitive interface.
Migrated the python functions dialog UI to shadCN, ensuring consistency
with the rest of the application's design.
Migrated the headlessUI tooltip to shadCN.
FYI: Need to improve the dialog subtitles texts.
This commit extracts the formatting methods for Azure and Llama fields from the `format_field` method to improve readability and maintainability of the code. The `format_azure_field` method formats the fields for Azure, while the `format_llama_field` method formats the fields for Llama. These methods are called conditionally based on the name of the field.
🐛 fix(API/index.ts): remove duplicate forward slash in API routes
The try-catch block was added to handle JSON parsing errors that may occur when parsing the cookieObject. This ensures that the application does not crash when such errors occur.
The duplicate forward slash in the API routes was removed to ensure that the routes are correctly formed and the API requests are sent to the correct endpoints.
🐛 fix(__main__.py): rename path variable to frontend_path for clarity
The first change fixes a type error for the multiprocess import. The second change renames the path variable to frontend_path to improve clarity and readability of the code.
🚀 feat(__main__.py): add optional open_browser argument to serve function to specify whether to open browser after starting server
The serve function now accepts an optional path argument to specify the path to the frontend directory containing build files. This is useful for development purposes only. The function also accepts an optional open_browser argument to specify whether to open the browser after starting the server. This is useful when running the server locally.
The code now checks if the streaming and stream attributes are boolean before setting them to True. This ensures that the attributes are not set to True if they are not boolean, which could cause errors in the code.
The abstractmethod decorator is redundant in the CustomChain and CustomAgentExecutor classes as the methods they decorate are already defined as abstract in the parent classes. Removing these decorators improves code readability and reduces clutter.
This commit makes the `function_name` and `initialize` methods abstract in the `CustomChain` and `CustomAgentExecutor` classes. This is done to enforce the implementation of these methods in the subclasses of these classes. This change improves the code quality and readability by making the code more explicit and easier to understand.
🐛 fix(interface/loading.py): fix custom_node instantiation to handle classes without initialize method
✨ feat(template/frontend_node/prompts.py): change type_name to match class name
✨ feat(template/frontend_node/tools.py): change type_name to match class name
🔥 chore(test_agents_template.py): remove test_agents_settings and update initialize_agent test
The vertex_type assignment in the Vertex class was not handling uppercase template types correctly. This has been fixed to handle both uppercase and lowercase types. The custom_node instantiation in the instantiate_class function was not handling classes without an initialize method correctly. This has been fixed to instantiate the class directly if the initialize method is not present. The type_name in the ZeroShotPromptNode and PythonFunctionToolNode classes have been changed to match the class name. The test_agents_settings test has been removed as it is no longer necessary and the initialize_agent test has been updated to match the new AgentInitializer class name.
🔨 refactor(base.py): add CustomAgentExecutor class and move CustomChain to base.py
🔨 refactor(custom_lists.py): update reference to CustomChain to CustomAgentExecutor
The CustomChain class has been renamed to CustomAgentExecutor to better reflect its purpose. The class has been moved to base.py and a new CustomAgentExecutor class has been added to custom.py. The reference to CustomChain in custom_lists.py has been updated to CustomAgentExecutor. These changes improve the semantics of the code and make it easier to understand the purpose of the classes.
✨ feat(langflow): add new chains to config.yaml and custom chains to interface/chains/custom.py
The following chains were added to the config.yaml file: RetrievalQA, RetrievalQAWithSourcesChain, QAWithSourcesChain, ConversationalRetrievalChain, and CombineDocsChain. These chains were added to improve the functionality of the application and provide more options for users.
In addition, custom chains were added to the interface/chains/custom.py file. The CombineDocsChain was added to allow users to combine multiple documents into a single document for use in the question answering chains. The QA_CHAIN_TYPES constant was also added to the frontend_node/constants.py file to provide a list of available question answering chain types.
🔀 refactor(custom_lists.py): merge CUSTOM_AGENTS and CUSTOM_CHAINS into CUSTOM_NODES
🔀 refactor(loading.py): add instantiate_chains function to instantiate chains
🔀 refactor(base.py): add CustomChain class
The changes add support for a new chain called load_qa_chain to CUSTOM_NODES. CUSTOM_AGENTS and CUSTOM_CHAINS are merged into CUSTOM_NODES. A new function called instantiate_chains is added to instantiate chains. A new class called CustomChain is added to the base.py file. This class is used to define a custom chain.
✨ feat(frontend_node): add extra fields to MemoryFrontendNode and ChainFrontendNode
The unused code in custom.py has been removed. The MemoryFrontendNode and ChainFrontendNode classes have been updated to include additional fields that are required for their respective templates. The MemoryFrontendNode now has a return_messages field, and the ChainFrontendNode now has a memory field. These fields are optional and can be toggled on or off as required.
